Cucumber: Clear localStorage after each scenario

Capybara 3.12.0+ automatically clears localStorage and sessionStorage after each test.

Capybara clears cookies before each scenario, but not other client-side data stores. If your app is using localStorage or sessionStorage, contents will bleed into the next scenario.

Use this hook to remove all site data after each scenario:

After do
  if Capybara.current_driver == :selenium && !Capybara.current_url.starts_with?('data:')
    page.execute_script <<-JAVASCRIPT
      localStorage.clear();
      sessionStorage.clear();
    JAVASCRIPT
  end
end
